Here is the layout of an example Class, can someone guide me on what's best practice when creating a subclass of NSObject?
class MyClass: NSObject {
var someProperty: NSString! = nil
override init() {
self.someProperty = "John"
super.init()
}
init(fromString string: NSString) {
self.someProperty = string
super.init()
}
}
Is this correct, am I following best practice here?
I wonder if I'm correctly setting up the initializers (one that sets the string to a default, and one which I can pass in a string)?
Should I call super.init() at the end of each of the initializers?
Should my more specific (the one that takes a string) initializer simply call self.init() at the end rather than super.init()?
What is the right way to set up the initializers in Swift when subclassing NSObject? - and how should I call the super init ?
This question (albeit in Objective C) suggests you should have an init, which you always call and simply set the properties in more specific inits: Objective-C Multiple Initialisers
I'm not Swift ninja but I would write MyClass as:
class MyClass: NSObject {
var someProperty: NSString // no need (!). It will be initialised from controller
init(fromString string: NSString) {
self.someProperty = string
super.init() // can actually be omitted in this example because will happen automatically.
}
convenience override init() {
self.init(fromString:"John") // calls above mentioned controller with default name
}
}
